An innovative scaled model to simulate the perimeter hole blasting in tunnel
The success of smooth blasting essentially depends on geological condition of rock. Also, in the perimeter hole, borehole pressures with light, well-distributed explosive loads are important to minimise overbreak. In order to simulate perimeter holes with scaled model test, the borehole pressure...

| description | The success of smooth blasting essentially depends on geological condition of rock. Also, in the
perimeter hole, borehole pressures with light, well-distributed explosive loads are important to
minimise overbreak. In order to simulate perimeter holes with scaled model test, the borehole
pressure was considered as a factor of scale. Hydraulic oil pressure is applied as borehole pressure
instead of using explosives and detonators in order to remove the undesirable effects of detonators
in an experimental set-up of just two perimeter holes in a tunnel blast. The borehole pressure on
a perimeter hole is nearly reproduced with hydraulic pressure which is generated by non-electric
detonators in the hermetical cylinder. |
